Definitions

  • This invention refers to improvements in pointer-controlled computer operations, and more specifically, to means for causing a computer to repeat a desired operation or series of operations by a reduced number of commands or by a single command, without interfering with the computer software.
  • it refers to means for causing a computer to repeat the transfer of print or graphic elements from one zone of the computer screen to another or for reproducing designs in any such zone, as well as for creating pointer commands that are not available in the computer toolbars or menus.
  • Patent application PCT/IL96/00078 describes improvements in pointer devices for operating computers in computer operation processes and in apparatus comprising computers and pointer devices.
  • Said PCT application also discloses pointer controlled computer apparatus, which comprises:
  • I a pointer device, comprising means for producing and transmitting to a computer at least signals corresponding to pointer index displacements and other desired information and instructions;
  • V means for reading and/or retrieving said differential displacements and determining from them reference counter coordinates
  • VI means for performing the operations corresponding to said reference counter coordinates.
  • the pointer to which said PCT application, as well as the present application, refers may be, and often is, a mouse; however, it may be any kind of pointer, and therefore, while reference may be, made to a mouse for descriptive purposes, it should be remembered that what is said about a mouse extends to any computer controlling pointers, and, conversely, that the term “pointer” includes a mouse. It should also be remembered that a pointer is represented on the computer screen by a pointer index or cursor (“index” and “cursor” being herein synonymous) and what is seen by the computer operator is the positions and displacements of said index, so that, when pointer positions or displacements are mentioned herein. what is intended are the positions or displacements of the pointer index. In computer operation, the pointer index may assume different shapes depending on the computer software, in particular the arrow shape, the I-shape and the L- or equivalent shape, said shapes and their changes have a significance well known to all persons who use computers.
  • the method and apparatus of the aforesaid PCT application associate to any operation, or series of operations, the succession of pointer events which cause them to be carried out by the computer. According to it, two Modes are available in the pointer-computer device and in its operation: the R/M (REGISTER/MEMORY) Mode and the A/P (ACTIVE/PLAY) Mode.
  • pointer (mouse) event is ordinarily used to mean the actuation of a pointer (or, in particular, mouse) key, or in general, any command given by means of a pointer, but in this specification and claims, it should be construed to further include any elementary X or Y displacement of the pointer or of the pointer index.
  • a pointer event is the transmission of a message or code from the pointer to the computer, which message or code is generally a digital one, composed of a number of bits.
  • the method and apparatus described in said PCT application permit, and in fact require, to register and memorize all pointer events—viz. the corresponding messages or codes—which are relevant for carrying out any desired computer operation and to “play”, viz. reproduce those same successions of events as if they originated at the moment from the pointer, whenever desired to carry out once again the same operation or succession of operations.
  • the computer believes, so to speak, that they originate from the pointer, and reacts accordingly.
  • the pointer may be used to define what will be called a “design”, viz. a geometric figure, a curve, a shaped surface or any regular or irregular graphic entity, on the computer screen.
  • a “design” viz. a geometric figure, a curve, a shaped surface or any regular or irregular graphic entity, on the computer screen.
  • Some computer programs are capable of memorizing an approximation of the path which the pointer has followed in defining the design, by memorizing the positions of the pointer at certain time intervals and by approximately reproducing the design as defined by the points at which the pointer was located at said time intervals.
  • the design is approximately memorized as a succession of segments, the length of which depends on the length of displacement of the pointer between the two successive times at which the position of the pointer has been memorized. It is apparent that in this way, the design is reproduced with an approximation that depends on the speed with which it has been generated by the pointer in its displacement. If the pointer has been moved fairly rapidly, the succession of segments will not adequately approximate the pointer path, and therefore the design itself and it will be necessary to generate it very slowly in order to reproduce it with reasonable accuracy. However, this is the best that present computer programs are capable of doing. It would be desirable to be able to reproduce graphic entities accurately, regardless of the speed with which. they are generated, and of their complexity. Further, it would be desirable to be able to reproduce a design in any chosen zone of the computer screen, even different from that in which the design has been generated. Present computer programs do not permit to so this.
  • a succession or series of pointer (mouse) events will be called “a pointer (mouse) output”.
  • An output may consist of any number, e or more, of events.
  • the displacement of the pointer cursor over the screen, resulting from a plurality of elementary displacements, each of which is an event, represents in itself an output.
  • a single elementary displacement along one coordinate axis is a “single-event pointer output”.
  • the computer receiving the pointer output, will translate it to an action (simple or complex) which depends on the computer software.
  • the computer system comprises instructions, generally stored in what is known as the “Service Library”, which determine how the computer should act when it receives a pointer output.
  • transfer operator since it creates a correspondence between pointer outputs and computer actions.
  • the action which the computer carries out in consequence of the application of the transfer operator to a given pointer output, will be called the action or the program response “associated” with that output, and, vice versa, the pointer output which gives rise, by the application of the transfer operator, to a given computer action or program response, will be called the output “associated” with that action or program response.
  • a pointer output causes no computer action, such being in general the case e.g. when a pointer key is depressed while the pointer index is located in a blank portion of the screen.
  • the transfer operator is the “zero operator” and that the associated action connected to such an output is a “zero action”.
  • the transfer operator depends on the computer, on the program which it uses, on the position of the pointer, and in some cases, on the pointer outputs and computer actions that have previously occurred It is in no way connected with the pointer hardware or software.
  • this invention must be computer- and software-independent, viz. must be, as to itself equally operative and effective no matter what the transfer operators, though its results may be and generally are influenced by the type of computer and its software.
  • the process according to the invention comprises the following steps:
  • the transfer operators included in the computer software will react to the repeated pointer events and outputs in the same manner in which they reacted when said events and outputs occurred for the first time, and in both cases the computer will carry out the action associated with said events and outputs.
  • the above operations may be carried out on a number of pointer outputs.
  • one of the possible pointer outputs will be selected at the beginning of the aforesaid process steps and said steps will be repeated for any other selected output; and in the A/P Mode a pointer output will be firstly selected from among those previously chosen in the R/M Mode, and the successive steps will be repeated for any successive, selected pointer output.
  • Said embodiments therefore, involve the steps of:
  • pointer events are generally produced by depressing or/and releasing pointer keys or, in the case events that are displacements, by displacing the pointer in a manner adapted to the particular pointer in use.
  • pointer events that occur in the process of the invention and which affect the operation of the pointer and not of the computer and therefore are not transformed to associated computer actions by a transfer operator.
  • pointer events are, generally, the identification of the beginning and of the end of a selected pointer output, the change from one Mode to the other, the selection, in the A/P Mode, of a pointer output from among those previously chosen in the R/M Mode, and others that may be provided by the invention.
  • Such pointer events may be caused by actuating a key or a combination of keys of the pointer or by actuating pointer keys in combination with a computer keyboard key, or, in some cases, by actuating a computer keyboard key or combination of keys. It should be understood, therefore, that the mention hereinafter of the way in which a pointer event is determined, is not binding, as the most suitable key or combination of keys will be adopted by the skilled person in each case.
  • a combination of two pointer keys may be used for changing from the AP Mode (which may, and in most cases does, automatically eat when the computer is switched on) to the R/M Mode and vice versa; and another such combination may be used for identifying the beginning and the end of a pointer output.
  • either the switch from the A/P to the R/M Mode and vice versa, or the identification of the beginning and of the end of a pointer output, or both may be effected by means of a key or combination of keys of the computer keyboard or combination of such keys with pointer keys. Actuating the keyboard keys will then produce codes having the same effect as if the codes were produced by pointer events.
  • the invention also provides pointer controlled computer apparatus, which comprises:
  • I a pointer device, comprising means for transmitting to a computer signals corresponding to all occurring pointer events
  • V means for causing the computer, when desired, to apply to any registered and memorized pointer output the corresponding transfer operator.
  • the apparatus will further comprise means for means for registering and memorizing a plurality of pointer outputs, means for selecting any desired pointer output, among said plurality, for registering and memorizing, and means for selecting any registered and memorized pointer output to be retrieved.
  • the apparatus ordinarily operates in overwrite manner, viz. if a first pointer output has been memorized in a memory bank comprised in the aforesaid means for registering and memorizing the selected pointer outputs, and the same registering and memorizing operations are repeated with reference to a second, different output, the second output replaces the first, which is canceled from said memory bank.
  • the memorized and reproduced pointer outputs can be varied at will, according to the requirements of the moment.
  • the outputs memorized in the memory bank comprised in the aforesaid means for registering and memorizing the selected pointer outputs may be canceled when the computer is switched off, thus clearing all the memory means for future operation, or they may be retained in spite of the switching off.
  • the hardware of the apparatus according to the invention may be the same as described and claimed in PCT/IL96/00078; particularly, it may be the hardware according to any embodiment of PCT/IL96/00078.
  • the means and actions for producing pointer events, described in said PCT application, are generally applicable to the present invention.
  • a single pointer output is to be registered and then repeated, it is, so to speak, automatically selected both in the R/M and in the A/P Mode, viz. its registration and repetition may be. started by actuating a key or combination of keys, and it may be that the same key or combination of keys may start registration or repetition, depending on whether the apparatus is in the R/M or in the A/P Mode.
  • any one of a plurality of pointer outputs is to be registered and then repeated when desired, an actual selection between different outputs must be carried out in both Modes and the selected memory bank or banks must be addressed in each case. This can be. done in various ways, readily carried into practice by skilled persons.
  • a rouse or keyboard key or combination of keys may be associated to each output, and each such key or combination of keys will cause the pointer to convey digital information to the appropriate key or combination of keys and to retrieve information therefor.
  • an output selector may be provided and the different outputs may be identified, e.g., by numerals.
  • the selector may be a key that switches from memory bank or banks at each successive actuation, a different identifying numeral being displayed each time in any convenient way, e.g., in a pointer window.
  • the selector may be a rotatable button, carrying different numerals about its periphery and associated with a reference index, which button switches from one memory bank or combination of banks to another as it is rotated from one angular position to another.
  • the selector may comprise a transistor or a transistor circuit. Al these and other switching means are per se conventional and need not be particularly described.
  • FIGS. 1 and 1 a schematically illustrate the pointer events and the associated actions of one embodiment of the process according to the invention, FIG. 1 referring to the R/M Mode and FIG. 1 a to the A/P Mode;
  • FIGS. 2 and 2 a are analogous to FIGS. 1 and 1 a , but refer to another embodiment of the process:
  • FIG. 3 illustrates in block diagram form one embodiment of the apparatus according to the invention.
  • FIGS. 4 and 5 schematically illustrate the operations carried out by the apparatus of FIG. 3, in the R/M and in the A/P Mode respectively.
  • Examples describe the memorization of only one pointer output, and therefore do not comprise a selector for selecting a desired output from a plurality thereof, but the extension of what is described to a plurality of outputs is obvious, it being sufficient that the apparatus be provided with a plurality of memory banks and with selector means for switching between them.
  • the transfer, by means of a pointer which is a mouse, of a graphic entity from a position on the computer screen to another is illustrated (with reference to FIG. 1 for the R/M Mode and to FIG. 1 a for the A/P Mode) by showing how letters, which have been printed in a certain succession, can be displaced, over the screen so as to undergo a permutation, changing and even totally inverting their order.
  • the operations described would permit to displace graphic entities also other than letters and to effect displacements that are different and/or have for other purposes and by means of a pointer other than a mouse.
  • the process of this example is illustrated by the succession of mouse events and the corresponding associated (computer) actions or program responses determined by the Transfer Operator. It should be noted that in all the stages of the process the letters ABCDEFGH occupy together they same area of the screen, though, for purposes of illustration, they are shown in different areas of the drawing sheet.
  • the progressive numerals in the first (left-hand side) column indicate the order in which the pointer (mouse) events and program responses follow one another, and the numerals, in parentheses, in the second column identify each event, whenever it occurs.
  • the event Middle Button Up is identified by (2′′) whenever it occurs, and in this Example it occurs for the first time as the fourth event.
  • FIG. 1 Mouse Events Associated Program Response 1 (1′) Middle Button Down 0 2 (2′) Right Button Down 0 3 (1′′) Right Button Up 0 4 (2′′) Middle Button Up 0
  • Event 1 causes the arrow shaped pointer index to move to the original point (e.g., in this example, the upper left corner of the screen) regardless of what might be the location of the pointer index (Xn,Yn) before the event occurs. Although this movement of the pointer index is visible, it does not depend on the-program currently being used (PowerPoint in this example). Therefore the Associate Program Response is zero.
  • the pointer index is brought to the location of the text where the editing to begin.
  • the arrow-shaped pointer index changes into a I-beam-shaped pointer index, since the presence of a text has been recognized by the program.

  • the Middle+Right Button combination sequence (as for events 1 to 4), in the example, operates in toggle Mode. Thus, this time, the sequence of events from 18 to 20 causes the mouse to stop recording mouse events. (R/M Mode Off)

Although this movement of the pointer index is visible, it does not depend on the program currently being used (PowerPoint in this example). Therefore, the Associated Program Response, at this point, is zero.
